Specification forming part of Letters Patent o. 130,028, dated July 30,1872.

To all whom it may concern:

Be it known that I, JESSE DYER, of Rouseville, in the county of Venaugoand State of Pennsylvania, have invented an Improved Wood Pavement; andI do hereby declare the following to be a full, clear, andexactdescription of the same, reference being had to the accompanying drawingforming part of this specification, in which Figure l is a perspectiveView; Fig. 2, a section taken longitudinally of the street; and Fig. 3,a section transverse to the street.

Similar letters of reference in the accompanying drawing indicate thesame parts.

,This invention is an improvement upon then well-known Staord pavement;and consists in using,in combination with the'keyed blocks and thetransverse key-pieces, a series of parallel longitudinal key-pieces,dovetailed into the under side of the transverse key-pieces, so i astolock them all together, substantially as hereinafter set forth. .i

I n the drawing, B B are the paving-blocks, constructed With a dovetailkey, m, on their lower ends. C C are the transverse key-pieces, used tospace the blocks and lock them down,

as shown in Figs. 1 and 2; and A A are the longitudinal key-pieces addedby me, said pieces being dovetailed into the under side of the pieces CG at right angles with them. The key-pieces G C are made comparativelynarrow and deep, and the key-pieces A A wide and thin, so that when thelatter are in position, as shown in the drawing, the blocks B'B can beslid into place without comingin contact with the lower foundation.

The result is that the pavement can be laid very rapidly, and when laidis strong, durable, and of uniform even surface, not only the i11-dividual blocks, but Whole rows of blocks being interlocked andconnected together in such a way that no block or row of blocks canstart up or down out of place so as to render the surface uneven.

Having thus described my invention, what I claim is- In a Wood pavementhaving the blocks B B and transverse pieces C C, constructed andcombined as described, the iiat longitudinal key-piecesAA, dovetailedinto the under side of the cross-pieces beneath the line of the blocks,substantially as described, for the pue poses speciiied.

JESSE DYER.
